使用Nginx实现简单的RTMP推流直播笔记

实现结果

推流的实现：使用OBS Studio进行推流
拉流播放的实现：使用VLC进行拉流地址播放
直播服务器实现：centos系统下的nginx+RTMP模块

实现步骤：

第1步：nginx相关依赖包的安装

nginx相关依赖包的安装：

yum install -y perl-ExtUtils-Embed readline-devel zlib-devel pam-devel libxml2-devel libxslt-devel openldap-devel python-devel gcc-c++   openssl-devel cmakepcre-develnanowget  gcc gcc-c++ ncurses-devel perl

其他需要用到的依赖包：

 yum -y install git
yum -y install nano
yum -y install wget

第2步：nginx-rtmp-module

nginx-rtmp-module,官方github地址

// 通过git clone 的方式下载到服务器上
[root~]# git clone https://github.com/arut/nginx-rtmp-module.git

第3步：安装Nginx服务器

1.下载Nginx解压，并安装rtmp和openssl的模块
PS:add-module=/data/bak/nginx-rtmp-module 中的/data/bak是自己的下载的相关模块的存放路径

[root~]# wget http://nginx.org/download/nginx-1.10.3.tar.gz 
[root~]# tar -zxvf nginx-1.10.3.tar.gz 
[root~]# cd nginx-1.10.3
//添加rtmp和openssl支持
[root~]# ./configure --add-module=/data/bak/nginx-rtmp-module --with-http_ssl_module
[root~]# make && make install

第4步：查看安装模块信息：

[root@localhost nginx-1.10.3]# ln -s /usr/local/nginx/sbin/nginx /usr/bin/nginx
[root@localhost nginx-1.10.3]# nginx -V
nginx version: nginx/1.10.3
built by gcc 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) 
built with OpenSSL 1.0.2k-fips  26 Jan 2017
TLS SNI support enabled
configure arguments: --add-module=/data/bak/nginx-rtmp-module --with-http_ssl_module

第5步：启动nginx,查看启动的情况

[root@localhost nginx-1.10.3]# nginx -s stop
[root@localhost nginx-1.10.3]# nginx
[root@localhost nginx-1.10.3]# curl http://192.168.74.128/







Welcome to nginx!
If you see this page, the nginx web server is successfully installed and
working. Further configuration is required.

For online documentation and support please refer to
nginx.org.

Commercial support is available at
nginx.com.

Thank you for using nginx.


[root@localhost nginx-1.10.3]# 

第6步：配置相关的模块信息修改nginx.conf

PS：注意是在http{}外进行添加：

rtmp {
    server {
        listen 1935;
        application rtmplive {
            live on;
            record off;
        }
        application vod {
        play /opt/video/vod;
        }

    }
}

完成的配置文件如下：

==
#user  nobody;
worker_processes  1;

#error_log  logs/error.log;
#error_log  logs/error.log  notice;
#error_log  logs/error.log  info;

#pid        logs/nginx.pid;


events {
    worker_connections  1024;
}


http {
    include       mime.types;
    default_type  application/octet-stream;

    #log_format  main  '$remote_addr - $remote_user [$time_local] "$request" '
    #                  '$status $body_bytes_sent "$http_referer" '
    #                  '"$http_user_agent" "$http_x_forwarded_for"';

    #access_log  logs/access.log  main;

    sendfile        on;
    #tcp_nopush     on;

    #keepalive_timeout  0;
    keepalive_timeout  65;

    #gzip  on;

    server {
        listen       80;
        server_name  localhost;

        #charset koi8-r;

        #access_log  logs/host.access.log  main;

        location /stat {     #第1处添加的location字段。
            rtmp_stat all;
            rtmp_stat_stylesheet stat.xsl;
        }

        location /stat.xsl { #第2处添加的location字段。
           root /usr/local/nginx/nginx-rtmp-module/;
        }

        location / {
            root   html;
            index  index.html index.htm;
        }

        #error_page  404              /404.html;

        # redirect server error pages to the static page /50x.html
        #
        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }

        # proxy the PHP scripts to Apache listening on 127.0.0.1:80
        #
        #location ~ \.php$ {
        #    proxy_pass   http://127.0.0.1;
        #}

        # pass the PHP scripts to FastCGI server listening on 127.0.0.1:9000
        #
        #location ~ \.php$ {
        #    root           html;
        #    fastcgi_pass   127.0.0.1:9000;
        #    fastcgi_index  index.php;
        #    fastcgi_param  SCRIPT_FILENAME  /scripts$fastcgi_script_name;
        #    include        fastcgi_params;
        #}

        # deny access to .htaccess files, if Apache's document root
        # concurs with nginx's one
        #
        #location ~ /\.ht {
        #    deny  all;
        #}
    }


    # another virtual host using mix of IP-, name-, and port-based configuration
    #
    #server {
    #    listen       8000;
    #    listen       somename:8080;
    #    server_name  somename  alias  another.alias;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}


    # HTTPS server
    #
    #server {
    #    listen       443 ssl;
    #    server_name  localhost;

    #    ssl_certificate      cert.pem;
    #    ssl_certificate_key  cert.key;

    #    ssl_session_cache    shared:SSL:1m;
    #    ssl_session_timeout  5m;

    #    ssl_ciphers  HIGH:!aNULL:!MD5;
    #    ssl_prefer_server_ciphers  on;

    #    location / {
    #        root   html;
    #        index  index.html index.htm;
    #    }
    #}

}

rtmp {
    server {
        listen 1935;
        application rtmplive {
            live on;
            record off;
        }
        application vod {
        play /opt/video/vod;
        }

    }
}

第7步：关闭防火墙，为方便测试

ps:一般线上环境是不会直接关闭防火墙，而是开放对应的端口。写对应的规则！

systemctl stop firewalld

第8步：重启的启动nginx,并用浏览器打开：http://192.168.74.128/stat

[root@localhost nginx-1.10.3]# nginx -s reload
[root@localhost nginx-1.10.3]# curl http://192.168.74.128/stat

第9步：使用OBS Studio进行推流

首先在PC端安装一下OBS Studio ：https://obsproject.com/download#mp

第10步：使用VLC播放器进行播放拉流地址

PS：使用另一种方式使用ffmpeg进行推流的实现，待验证：
